Abstract
A spraying and dust removing device for a blackboard is characterized in that the device comprises a blast mist chamber (1) and a blast mist pipe (2) communicated with the blast mist chamber (1) and horizontally arranged above the blackboard, wherein an ultrasonic sprayer (3) and a blast mist fan (4) are mounted inside the blast mist chamber (1); a plurality of spray nozzles (5) are arranged on the blast mist pipe (2); a spraying switch (6) is arranged beside the blackboard; and the ultrasonic sprayer (3) and the blast mist fan (4) are connected to commercial power through a blast mist switch (6) after being connected in parallel with a circuit. The spraying and dust removing device for the blackboard has the advantages that the practicability is strong, mist spray is used for condensing dust produced during blackboard erasing rapidly, environment pollutions and harms to human body caused by diffusion of falling dust can be reduced, the speed is fast, the efficiency is high, and the spraying and dust removing device for the blackboard is classified as optimal teaching auxiliary equipment.
Description
Technical field
The utility model relates to the blackboard peripheral equipment, is a kind of blackboard spray dust remover specifically.
Background technology
Traditional school instruction mode still adopts blackboard to add chalk, and erase the board the powder ash kicked up not only severe contamination environment, and teachers and students healthy also caused serious injury, for dedusting with reduce the harm that dust brings, people want to have use up way, yet it is little to produce effects.In the face of the demand in market, for environment and teachers and students' health, need a kind of spray dust remover efficiently of exploitation in a hurry simultaneously.
Summary of the invention
The purpose of this utility model provides a kind of blackboard spray dust remover of highly effective.
Described blackboard spray dust remover is characterized in that: this device comprises that bulging fog chamber reaches the bulging mist pipe that is communicated with, is lying in the blackboard top with the drum fog chamber; Ultrasonic sprayer and drum mist fan are housed in the described bulging fog chamber; Described bulging mist pipe is provided with a plurality of spray nozzles; The other spray switch that is provided with of blackboard; Ultrasonic sprayer and drum mist fan are by being connected to civil power by spray switch after the circuit parallel connection.
The utility model is practical, and the dust that utilizes spraying to condense rapidly and produce when erasing the board reduces because the environmental pollution that the diffusion of dust causes and to the injury of human body rapidly and efficiently, is the auxilliary religion equipment of school's the best in fact.
Description of drawings
Fig. 1 is the utility model structural representation,
Fig. 2 is the utility model electrical principle block diagram.
Among the figure: 1-drum fog chamber, 2-drum mist pipe, 3-ultrasonic sprayer, 4-drum mist fan, 5-spray nozzle, 6-spray switch.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further specified: blackboard spray dust remover as shown in fig. 1, this device comprise bulging fog chamber 1 and with bulging mist pipe 2 above drum fog chamber 1 is communicated with, is lying in blackboard; Ultrasonic sprayer 3 and drum mist fan 4 are housed in the described bulging fog chamber 1; Described bulging mist pipe 2 is provided with a plurality of spray nozzles 5; The other spray switch 6 that is provided with of blackboard; Ultrasonic sprayer 3 and drum mist fan 4 are by being connected to civil power by spray switch 6 after the circuit parallel connection.
Described ultrasonic sprayer 3 has been matured product, is widely used in that air humidification, vegetables and fruits are preserved moisture, beauty treatment etc.Its operation principle is: utilize hydroecium bottom transducer (ultrasonic oscillator) to convert electric energy to mechanical energy, Xiang Shuizhong launches the ultrasonic wave of 1.7MHz, and making water surface produce diameter under the effect of cavitation effect is the ultramicron of 3-5 μ m, thereby produces fog.
As shown in Figure 1, operating process of the present utility model is:
When needs erase the board, press spray switch 6, this moment, circuit powered on, and started working.
In drum fog chamber 1, ultrasonic sprayer 3 energising backs produce fog, and drum mist fan 4 rotates, and fog is advanced bulging mist pipe 2 by drum, again from spray nozzle 5 ejections, thereby form one fog barrier before blackboard, isolate the diffusion of dust, and the powder ash that condenses rapidly simultaneously falls.After the powder ash is removed totally, close spray switch 6 again, equipment quits work.
